Update the drivers to pass the RSSI level as a cfg80211_cqm_rssi_notify parameter and pass this value to userspace in a new nl80211 attribute. This helps both userspace and also helps in the implementation of the multiple RSSI thresholds CQM mechanism. Note for marvell/mwifiex I pass 0 for the RSSI value because the new RSSI value is not available to the driver at the time of the cfg80211_cqm_rssi_notify call, but the driver queries the new value immediately after that, so it is actually available just a moment later if we wanted to defer caling cfg80211_cqm_rssi_notify until that moment. Without this, the new cfg80211 code (patch 3) will call .get_station which will send a duplicate HostCmd_CMD_RSSI_INFO command to the hardware.

Extend ieee80211_cqm_rssi_notify with a rssi_level parameter so that this information can be passed to netlink clients in the next patch, if available. Most drivers will have this value at hand. wl1251 receives events from the firmware that only tell it whether latest measurement is above or below threshold so we don't pass any value at this time (parameter is 0).

For wowlan netdetect a separate limit is defined for the number of matchsets. Currently, this limit is ignored and the regular limit for scheduled scan matchsets, ie. struct wiphy::max_match_sets, is used for the net-detect case as well.

Instead of open coding the CMAC algorithm in the mac80211 driver using byte wide xors and calls into the crypto layer for each block of data, instantiate a cmac(aes) synchronous hash and pass all the data into it directly. This does not only simplify the code, it also allows the use of more efficient and more secure implementations, especially on platforms where SIMD ciphers have a considerable setup cost.

Switch the FILS AEAD code to use a cmac(aes) shash instantiated by the crypto API rather than reusing the open coded implementation in aes_cmac_vector(). This makes the code more understandable, and allows platforms to implement cmac(aes) in a more secure (*) and efficient way than is typically possible when using the AES cipher directly. So replace the crypto_cipher by a crypto_shash, and update the aes_s2v() routine to call the shash interface directly. * In particular, the generic table based AES implementation is sensitive to known-plaintext timing attacks on the key, to which AES based MAC algorithms are especially vulnerable, given that their plaintext is not usually secret. Time invariant alternatives are available (e.g., based on SIMD algorithms), but may incur a setup cost that is prohibitive when operating on a single block at a time, which is why they don't usually expose the cipher API.

The spec writes cipher/AKM suites as something like 00-0F-AC:9, but the part after the colon isn't hex, it's decimal, so that we've already had a few mistakes (in other code, or unmerged patches) to e.g. write 0x000FAC10 instead of 0x000FAC0A.

There are no users of this ("vrfkill") in the tree, so it's just dead code - remove it. This also isn't really how rfkill is supposed to be used - it's intended as a signalling mechanism to/from the device, which the driver (and partially cfg80211) will handle - having a separate rfkill instance for a regulator is confusing, the driver should use the regulator instead to turn off the device when requested.

Daniel Mack says: ==================== bpf: add longest prefix match map This patch set adds a longest prefix match algorithm that can be used to match IP addresses to a stored set of ranges. It is exposed as a bpf map type. Internally, data is stored in an unbalanced tree of nodes that has a maximum height of n, where n is the prefixlen the trie was created with. Note that this has nothing to do with fib or fib6 and is in no way meant to replace or share code with it. It's rather a much simpler implementation that is specifically written with bpf maps in mind. Patch 1/2 adds the implementation, 2/2 an extensive test suite and 3/3 has benchmarking code for the new trie type. Feedback is much appreciated. Changelog: v3 -> v4: * David added a 3rd patch that augments map_perf_test for LPM trie benchmarks * Limit allocation of maps of this new type to CAP_SYS_ADMIN for now, as requested by Alexei * Add a stub .map_delete_elem so the core does not stumble over a NULL pointer when the syscall is invoked * Tests for non-power-of-2 prefix lengths were added * More comment style fixes v2 -> v3: * Store both the key match data and the caller provided value in the same byte array attached to a node. This avoids double allocations * Bring back node->flags to distinguish between 'real' and intermediate nodes * Fix comment style and some typos v1 -> v2: * Turn spin lock into raw spinlock * Lock with irqsave options during trie_update_elem() * Return -ENOMEM properly from trie_alloc() * Force attr->flags == BPF_F_NO_PREALLOC during creation * Set trie->map.pages after creation to account for map memory * Allow arbitrary value sizes * Removed node->flags and denode intermediate nodes through node->value == NULL instead rfc -> v1: * Add __rcu pointer annotations to make sparse happy * Fold _lpm_trie_find_target_node() into its only caller * Fix some minor documentation issues ==================== Signed-off-by: NDavid S.

Extend the map_perf_test_{user,kern}.c infrastructure to stress test lpm-trie lookups. We hook into the kprobe on sys_gettid() and measure the latency depending on trie size and lookup count. On my Intel Haswell i7-6400U, a single gettid() syscall with an empty bpf program takes roughly 6.5us on my system. Lookups in empty tries take ~1.8us on first try, ~0.9us on retries. Lookups in tries with 8192 entries take ~7.1us (on the first _and_ any subsequent try).

The first part of this program runs randomized tests against the lpm-bpf-map. It implements a "Trivial Longest Prefix Match" (tlpm) based on simple, linear, single linked lists. The implementation should be pretty straightforward. Based on tlpm, this inserts randomized data into bpf-lpm-maps and verifies the trie-based bpf-map implementation behaves the same way as tlpm. The second part uses 'real world' IPv4 and IPv6 addresses and tests the trie with those.

Internally, data is stored in an unbalanced trie of nodes that has a maximum height of n, where n is the prefixlen the trie was created with. Tries may be created with prefix lengths that are multiples of 8, in the range from 8 to 2048. The key used for lookup and update operations is a struct bpf_lpm_trie_key, and the value is a uint64_t.

The EMAC has an internal PHY that is often called the "SGMII". This SGMII is also connected to an external PHY, which is managed by phylib. These dual PHYs often cause confusion. In this case, the data structure for managing the SGMII was mis-named and located in the wrong header file. Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies to the internal PHY only. It also also moved from emac_phy.h (which supports the external PHY) to emac_sgmii.h (where it belongs). To keep the changes minimal, only the structure name is changed, not the names of any variables of that type. Signed-off-by: NTimur Tabi <timur@codeaurora.org> Signed-off-by: NDavid S.
